摘要
The Jurassic Shalitashi Formation is one of the most important coal-bearing formations in Mazar area,western Kunlun,Xinjiang.Based on analyzing the characteristics of lithofacies,stratigraphic contact relationship,depositional environment,grain-size and sedimentary facies,this paper considers that the sedimentary facies of Shalitashi Formation can be divided into fan delta facies,river-lake facies and braided river delta facies,experienced the evolution of "chasmic stage-stable stage-closed stage".The new discovery of several large-scale asphalt veins indicates that the sedimentary Shalitashi Formation of Ye’erqiang Group may have a good prospect for prospecting of coal and oil-gas reservoirs.
